Inferring Human-Robot Performance Objectives During Locomotion Using Inverse Reinforcement Learning and Inverse Optimal Control

IEEE ROBOTICS AND AUTOMATION LETTERS, 7(2), 2549–2556.

By: W. Liu  n, J. Zhong *, R. Wu *, B. Fylstra n, J. Si* & H. Huang n 

Contributors: W. Liu n, J. Zhong *, R. Wu *, B. Fylstra n, J. Si* & H. Huang n 

author keywords: Learning from demonstration; reinforcement learning; wearable robotics
TL;DR: This study proposes a new inverse approach from observed human-robot walking behavior to infer a human- robot collective performance objective represented in a quadratic form and introduces a new tool to the field of wearable lower limb robots. (via Semantic Scholar)
